There are a few things we could do to speed up processing 690,000 files, but we need a few more details to come up with something that stands a chance of working correctly and reasonably quickly. (Nothing reading 690,000 files is going to be quick, but there may be a difference between slow and SSSSLLLLLOOOOWWWW.)
  1. Do any of the filenames you need to move contain any of the characters, <space>, <tab>, <newline>, <single-quote>, or <double-quote>? If so, which of these characters might appear in your filenames? If some of these characters do appear in your filenames, do they appear in all of your filenames? If not, how many of your filenames (that will be moved) will contain any of these characters?
  2. Are all of the files you need to evaluate:
    • in a single directory?
    • in a single directory hierarchy?
    • in several single directories?
    • in several directory hierarchies?
    If they are in single directories, do any of those directories contain any subdirectories?
  3. Are all of the selected files going to a single directory? Or, if the files are coming from a directory hierarchy, is the hierarchy to be copied to the destination directory?
  4. What is the minimum size, maximum size, and approximate average size (in bytes) of the files you need to evaluate?
  5. Is it really true that all that needs to be checked is that there are three or more hyphens on the 3rd line of a file, or do we need to verify that the line starts with a [, ends with a ], and contains at least three hyphens surrounded by one of more lowercase letters?
  6. Out of the 690,000 files you need to process; how many do you expect will be moved?

dh_movefiles

DH_MOVEFILES(1) 						     Debhelper							   DH_MOVEFILES(1)

NAME

       dh_movefiles - move files out of debian/tmp into subpackages

SYNOPSIS

       dh_movefiles [debhelperoptions] [--sourcedir=dir] [-Xitem] [file...]

DESCRIPTION

       dh_movefiles is a debhelper program that is responsible for moving files out of debian/tmp or some other directory and into other package
       build directories. This may be useful if your package has a Makefile that installs everything into debian/tmp, and you need to break that
       up into subpackages.

       Note: dh_install is a much better program, and you are recommended to use it instead of dh_movefiles.

FILES

       debian/package.files
	   Lists the files to be moved into a package, separated by whitespace. The filenames listed should be relative to debian/tmp/. You can
	   also list directory names, and the whole directory will be moved.

OPTIONS

       --sourcedir=dir
	   Instead of moving files out of debian/tmp (the default), this option makes it move files out of some other directory. Since the entire
	   contents of the sourcedir is moved, specifying something like --sourcedir=/ is very unsafe, so to prevent mistakes, the sourcedir must
	   be a relative filename; it cannot begin with a `/'.

       -Xitem, --exclude=item
	   Exclude files that contain item anywhere in their filename from being installed.

       file ...
	   Lists files to move. The filenames listed should be relative to debian/tmp/. You can also list directory names, and the whole directory
	   will be moved. It is an error to list files here unless you use -p, -i, or -a to tell dh_movefiles which subpackage to put them in.

NOTES

       Note that files are always moved out of debian/tmp by default (even if you have instructed debhelper to use a compatibility level higher
       than one, which does not otherwise use debian/tmp for anything at all). The idea behind this is that the package that is being built can be
       told to install into debian/tmp, and then files can be moved by dh_movefiles from that directory. Any files or directories that remain are
       ignored, and get deleted by dh_clean later.

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
